8. We have analyzed the Me/Al ratio both by determining methyl according to the volumetric method used by Sinn and co-workers and the NMR method described by Imhoff and co-workers. We obtained an Me/Al value for our samples of "dried" commercial type MAO between 1.50 and 1.55, close to the nominal value of 1.5 often stated, clearly below the "as received" samples of ca. 1.7 and sigificantly above the samples studied by Barron and co-workers (see ref 7 and references therein). The analyses of the MAO samples are discussed in refs 2a and 2b.

11. By the term "react" we mean a reaction in the thermodynamic sense. In other words, from this term we exclude methyl exchanges and other dynamic rearrangements, such as TMA exchange.
